Title:
BEAM FAILURE REQUEST SENDING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/056550
Kind Code:
A1
Abstract:
Provided is a beam failure request sending method, which is applicable to a terminal. The method comprises: when a beam failure occurs in a secondary cell in a serving cell, determining a first resource for sending a beam failure request in a physical uplink control channel; determining whether a second resource occupied by other signaling which needs to be sent by means of the physical uplink control channel overlaps the first resource; and if the second resource overlaps the first resource, sending the beam failure request on at least the first resource. According to the embodiments of the present disclosure, in the case where a second resource for sending other signaling overlaps a first resource for sending a beam failure request, the beam failure request can be sent on at least the first resource, thereby ensuring that a base station is able to allocate a physical uplink shared channel resource to a terminal so as to send information about a beam failure, so as to realize beam failure recovery.
